Boundaries on Neutrino Mass from Supernovae Neutronization Burst by Liquid Argon Experiments

Original · EN

This work presents an upper bound on the neutrino mass using the emission of νₑ from the neutronization burst of a core collapsing supernova at 10 kpc of distance and a progenitor star of 15 M. The calculations were done considering a 34 kton Liquid Argon Time Projection Chamber similar to the Far Detector proposal of the Long Baseline Neutrino Experiment (LBNE). We have performed a Monte Carlo simulation for the number of events integrated in 5 ms bins. Our results are mν<2.71 eV and 0.18 eV<mν<1.70 eV, at 95% C.L, assuming normal hierarchy and inverted hierarchy, respectively. We have analysed different configurations for the detector performance resulting in neutrino mass bound of O(1) eV.
